Search Page - Why is there an "Upload Images" button?

That is a bug. The search function on ProBoards, unlike Google, does not allow you to search by image. If it did, that would be really great, but not going to happen. Somehow the same subroutine used for uploading images got referenced here.

I'll try to look into it later this month. But no guarantees anything can be done about it. Most of the code is pre-written or ported in with little or no documentation. The risk of doing a simple change there, is that it might affect some other miniscule electric car firmware in Asia, causing a reset, that in turn causes Austria Post to start printing stamps on toilet paper. Uh, wait...

Until then, don't hit return -- manually click on the "Search" button.

Thanks for letting us know.
