When you are not logged on, you don't see the uploaded images but their filenames (that I have no problem with). But when you are logged on, you see the images only and not the filenames. The URL of the images are changed to something like httq://club.cdfreaks.com/attachment.php?attachmentid=41892&stc=1 which has no original filename as part of URL. I would like to suggest that the original filename should be added to TITLE or ALT tag so that you can see quickly what the filename is by just hovering the mouse pointer over the image. Currently the only way to find out what the filename is (if you are logged in) is to do "Save Image As...". I don't know how that's possible becuase the filename doesn't appear to be part of the HTML (any ideas where it is stored, Web experts?).
Now the reason for having the filename shown. I think it could give some clue about the image. It could contain some useful info which is not mentioned in the post.
Some might not see the need for it. But I think it is better than not to have it and shouldn't be difficult to modify the forum code to add it to TITLE or ALT as they both are blank at the moment.
BTW, I have a question about referring to uploaded images in another post. How can you do that? Say you've uploaded an image in a post and want it to show in another post without re-uploading the same image again.
