Hi guys,
Well after quite a bit of searching through these forums, I finally found the solution in words I could understand (doh - sorry guys, having a bad few days)!
So this is the SIMPLE solution to making an image clickable and linking it to another website/URL etc.
The following is copied from notes I've made for myself!
-------------------------------------
OK, Firstly, this relates to the site: http://wordpress.com - ONLY!
To link an image to a webpage, it's important to remember the following:
1) If using Paypal (for example) - the link required will be the Email link and NOT the html link for a website.
2) The following link is based on uploading an image to your WordPress.com account first (Dashboard/Write)
3) Once you've uploaded the image, write down or copy the URL of your image file (it'll be found in the Dashboard - Manage/Uploads - and then double click the image you've just uploaded to display the html link information of your image).
4) Go to Presentation/Sidebar Widgets and add a Text Widget for the linked Image file you're about to create.
5) Now simply add a link in the following format inside the TEXT widget:
<a href="insert website link here"><img src="insert picture file link here including file extension.gif"></a>
-------------------------------------
If anyone is still not sure, please post back here and I'll run you through it step-by-step.
Thanks for all the support everyone.
Have a great week
Steve
