Deleting files from the media library

  1. Hi, I would like to ask, will my photos on my blog still be visible to everyone if I delete them from my media library?

    The blog I need help with is crystalwee.wordpress.com.

  2. No. If you delete any image from your Media Library then when a visitor's browser calls for it to be displayed there will be nothing to display.

  3. So there is no solution other than buying the space upgrade?

  4. Every WordPress.com blog has 3000 megabytes (~3 GBs) of space for storing uploaded files and images. I've been here 5 1/2 years and have only used 39.7 MB used, 3.0 GB (98.7%) upload space remaining. The blog linked to your username is empty - devoid on content so it still has 3000 megabytes (~3 GBs) of space for storing uploaded files and images.

    If you still think this is an issue there is lots of free image hosting online that you can get an account with and then link to your images kept on their servers from your blog.

  5. Optimizing the images is also important, both for saving storage space (3GB) and for making loading time faster:
    http://en.support.wordpress.com/media/image-optimization/

    I have 3,793 images on one blog, with 93% space still available.

  6. About the compressing matter, and the pigeon example in the link 1tess gives.

    It says there:

    Simply making an image smaller while editing a page does not necessarily make the file size smaller.
    You need to optimize the image.

    I don't understand the first line, and the second doesn't say HOW to optimize. Unless the instructor means reducing and correcting in for instance Irfanview?

  7. I've been blogging here for six years, uploading an average of about four images a day and I haven't hit my limit yet. Don't worry about it.

    And you need to make it a resolution of 72dpi or so for the web. That's what optimizing means.

  8. The link I gave has a short list of software to use to optimize your images:
    Image Editing Software

    Some have easy options to size and compress a batch of photos very quickly.

    Packages such as Photoshop / Paint Shop Pro will do it, but there is no need to spend money on doing this. These are free:

    Irfanview
    Picasa
    GIMP
    Photofiltre
    FastStone
    Pixia

    I'm not familiar with Irfanview, but if it can reduce your file size, then you have no need to worry. You can get perfectly fine images under 100 KB, or even better for download time, under 50 KB.

  9. There are 2 things you can do to do to get the file size of each image down:

    - change the resolution down to 72 dpi - anything more than that is wasted
    - change the size of the image (e.g. from 20" x 20" to 5" x 5")

    You might want to do both. Give it a shot and see how much space saving you yet get from just doing each one, and from both.

    Both of these changes will require an application to help you do this as 1tess says. (If you already have Photoshop you can automate this process and squish a bunch of photos at the same time.)

  10. Another useful bit of information to know about when optimizing images is the maximum width of your theme.

    There is no point in uploading an image wider than what your theme allows: best to upload a correctly sized image so that it does not have to be re-sized by wp.com:

  11. change the resolution down to 72 dpi - anything more than that is wasted

    Heatherstark, in Irfanview Properties I have it set at Base 768x512 pixels.

    I found on the web a calculator, and it shows that 375 pixels equal the 5" you mention. And these are based on 75 dbi.

    My template can handle a maximum width between 460-475 pixels ( I would have to try it out to know the exact max before the picture starts to creep under the widget segment), but I usually keep to 375 and less.

    I could set the value in Irfanview more strict; at Base/4 - 384x256 pixels, but sometimes a picture really needs 425 or even 450, hence my Base-768 choice.

    So I assume that at the setting of 72-75 dpi, the more an image extends a width of 375, the more it will loose in quality? Or does cover the Base-768 that sufficiently?

    With 3 GB I do not worry over space, I just want the best quality. What is advisable in my case? Set the values at Base 385, or 768? Or should I take this question to the Irfanview Forum?

    Those who are interested in that online converter, it can be found here:
    http://tiporama.com/tools/pixels_inches.html

  12. That converter you found has to do with printing. When you're talking web, you should only be concerned with pixel width: thinking about inches is pointless, because how many pixels will make an inch depends on each viewer's screen resolution.

    The facts are that browsers and screens display images at a resolution of 72, and that images downsized by WP lose quality. So for best quality downsize copies of your images to a resolution of 72 and to the desired pixel width (not exceeding the maximum for the theme you're using), and upload and insert those versions selecting the Full Size option. See the links Tess gave right before your post.

  13. How many pixels per inch equates to 72dpi?

  14. I saw Output to monitors/printers...

    Your best-quality advice is exactly how I have been doing it from the beginning. I also never resize in WP and keep Full Size checked. So, no further worries on my side. Except that I still do not know if I have to set the values at Base 385 or leave them at 768. Perhaps it makes no difference?

  15. @sgreifwonder: Sorry, I'm a Mac user, so I'm not familiar with Irfanview and don't know what Base/x means in that application. Perhaps another volunteer can answer your question.

    "is exactly how I have been doing it from the beginning": Yes, I had seen that (assuming your blog is http://sgreifwonder.wordpress.com/ ).* Doing this has other advantages too: your page loads faster, and you don't waste your storage space.

    * You should always link to your blog when you start a thread (or first show up in a thread) with a question. Or, better, make your username link to your blog (Users > Personal Settings: scroll down to Account Details, paste blog URL in the Website field, click Save Changes).

    As for "Output to monitors", the page includes this so you can get an idea of how large an image will look in your monitor, put this is of little practical use when you're interested in the width of images in relation to the theme you're using. As you have realized, what you need to know is the pixel width of your main column, to prepare your images accordingly.

  16. Or, better, make your username link to your blog (Users > Personal Settings: scroll down to Account Details

    @panaghiotisadam, due to the Over 12 and Adult marking, my name here doesn't link through to my blogs. It's an administration policy. There must be many more WP bloggers who carry this specification, but I seem to be the only one who is always told, 'Make your name linkable'...

    I usually put the webloglink in my forum posts (the admin policy obviously doesn't object to that), but I admit, I also often forget it.

    As you have realized, what you need to know is the pixel width of your main column, to prepare your images accordingly.

    I have Dusk, don't know its template pixel width but I guess that with 375-425 pixel images, I stay on the safe side.

  17. Adult? Sorry then, wrong suggestion!

    As for Dusk, I had already suggested in my first reply that you consult the links Tess gave:
    http://wpbtips.wordpress.com/2009/07/23/maximum-image-width/

  18. Not p@orn@graphy, I just do not blog for kiddies.
    Thanks for the reminder, panaghiotisadam, I obviously overlooked that link.
