I also have a .csv file with the name of a jpeg in one column and a text description of each jpeg in a second column. Is there a way to automatically insert one jpeg (photo) and its corresponding text, each pair on one page, into a Indesign document?
Read about Data Merge in the help files.
I would also recommend to write the description into the meta data. This would allow to place a text frame above the image and it is possible to add meta information and file name automatically together with the image, when you place it or even in a prepared template.
Meta data information can be written easily in Bridge in the Meta File Workspace.
