When you edited your photos--actually, any time a member edits their photos--they go from "Approved" status to "Pending Approval" again. This is to just ensure that someone isn't being a Sneaky Pete and uploading inappropriate images to a model that's already been approved.
I'll get your models approved in just a few minutes. I would have done it sooner, but I've been out of town for the last two days for work.
EDIT: I've just been through and approved everything that's approvable. Everything that's still not approved either has a case of the red X's (spriggan, zaku_ace, dean_zala, and others) or they didn't upload any images to it (neo_sigma).
To fix the red X problem, you need to go in and make sure you have thumbnails saved on your gallery submissions. All I'm getting--and I suspect all that's being seen here on this page under your "Modeler's Gallery" is an empty box with a red X. In other words, a bad image link. Here's what you do to fix it:
1. Click on the EDIT link under your picture.
2. Drag the red hatched box over whatever you want to be the thumbnail in that picture.
3. Click "DONE" in that same window once you've selected a thumbnail area.
4. Click "Save & Finish". Once I see that you've got a thumbnail up, I'll approve the entry.
