Unable to Upload Images Post Processing

Some exhibits are added without the image. I had one the other day.

Anyone else have problems uploading gifs to their gallery? Tried Firefox and Chrome both were unsuccessful.

Ran into this with 3 particular images I was trying to add to one of my sections. Eventually got all 3 to upload but it took an inordinate amount of time and numerous attempts. Have never seen this type of error before.

It seems to be happening again. I can make a new exhibit, but not upload images.

you have to upload images in JPEG, you can use "Paint" from windows and save as jpeg format
