What software are you using?
Also two other options for you to check out for image hosting are:
DeviantArt and Nikon's ImageSpace
Both are free(or have free account systems).
Because you have a Nikon camera body, the free ImageSpace account is larger than it otherwise would be if you didn't have Nikon camera.
I've never had an issue with DA in the ten years I've used it.
But I sometimes have linking issues with ImageSpace, only in that the transfer of the image from IS to the site you linked too can be slow. Hopefully they've fixed that.
The last option I (prefer to)use is AP's gallery space if it's just for linking to AP.
