I'm definitely NO expert but I've had the small type problem too.. advice that I got in the forum helped me to put it right... lets hope my very basic and very very limited knowledge can help...
You have your post open in the dashboard for "edit post".. on the right side of the screen you will see two tabs, one says " visual" the other says " HTML".
If you have it open in Visual, then photos will display .. as normal looking photos should..... you see the picture that makes sense to people...
Now you have it open in HTML, then the photo will show as a long link of text... code gobbledy gook computer stuff that makes sense to computers... like this:
[caption id="attachment_4284" align="aligncenter" width="360" caption="(photo © kiwidutch)"]<img class="size-full wp-image-4284" title="Sackville waterfowl2i (Small)" src="http://kiwidutch.wordpress.com/files/2009/12/sackville-waterfowl2i-small.jpg" alt="" width="360" height="480" />[/caption]
Ok,, now the text... click on your post in the HTML format and you will see more of that gobbledy gook stuff all around your text, somewhere in there will be the words " small" or "tiny" with lots of " <<" and ">>" thingys.. just select and edit out these. leaving your original text intact. Save and et voila the text should be back into normal size. ( well at least worked when I had the problem in my posts)
Yep, thereIS a quicker more direct and technical way to put this but I don't have the computer skills to tell you how in techno-speak,
Hope this makes sense anyway.. and hope it works for you. :)
cheers.... kiwidutch.
