Jpg/png image not uploading


I am trying to set the website slide show. I am able to create a new slide show. however when i try to add an image (jpg or png) size is 551k and image dimensions are 900x600, i am able to add the image, when i click upload, the webpage returns to the add slide show without the image being attached. No error message is displayed. I do not find the image listed in the uploaded files list either.

I have removed the EXIF information from the files.

How do I add slides to the slide show?

While uploading, are you selecting Private File tick box ?

No I have not checked the Private File tick box?
