Bug 28576: Add patron image in patron detail section does not specify image size limit

When you try to add an image to a patron in Home/Patrons/anyPatron, it only states the file types that are supported but not the maximum size. If you try to add an image that is bigger than 500 kb, nothing happens and the reason is not presented.

This is not the case with the 2 other places where we can add patron images in which they give warnings:
Home/Tools/Upload patron images
Home/Tools/Patron card creator/Images

For now, i simply added the size limit to the file supported message.

To test:
1)Search for any patron and go to his page
2)Hover over the image area on the left and click on add
3)Notice the message above the choose file button only specifies file types not size.
4)Add an image bigger than 500 kb
5)Nothing happens
6)Apply patch
7)Repeat steps from 1 to 3
8)Notice the message now includes the maximum size
