A quick update to my previous post Batch converting PDF to JPG/JPEG using free software about converting multiple files.
Instead of using convert, one can use the command mogrify:
mogrify -format jpg *.gif
These commands are from the fantastic suite of software known as ImageMagick.
I’m using this to convert the fantastic icons from famfamfam to gif as IE6 (running as the browser of choice on NHS computers - my target browser sadly) has problems with PNG format graphics. This is for my all singing all dancing WebObjects based medical research / patient record online system that is being deployed this month for the first time.
