I think I am getting closer. I used the checkbox file and received the following errors:
2009-11-19 08:37:25 3.csv 2 / 2 Import Error: Invalid File Download
URL is not readable or does not exist: http://22.214.171.124/omeka/images/3.jpg
I copy each URL to the browser and get the following message:
The document name you requested (/omeka/images/3.jpg) could not be found on this server. However, we found documents with names similar to the one you requested.
/omeka/images/2.jpg (mistyped character)
/omeka/images/1.jpg (mistyped character)
However, I return to my spreadsheet and copy each URL to the browser and able to 'download' the image.
Again, thank you.
