Error in image display

I am using Omeka Classic Version 3.0.3 and have issues using The Daily and Big Picture themes.
When I click on the images (photographs I took) that I have uploaded in the exhibits, the following page appears (instead of displaying the individual image in bigger size).

Can someone please help me fix this issue?
