Furgather Photo Issue

I been on Furgather for a short time, and ever since I joined I had this nagging problem of uploading photos. Although I never had that problem with any other site other than Furgather. So after posting a few low res images, it finally dawned upon me, there was a solution. You see the photos I take average around 4MB each, so I used the free photo program GIMP to bring them down to under 500K. Did a test, they now upload.
