Thanks guys. As usual I harnessed the might of the smart guys in the apple community (I'm just a user after all!)
The pictures were downloaded from the interweb onto my eeePC 501 windows netbook. I then converted them into GIF format. Next, using CiderPress I copied them into Apple II disk images on the 501. Then I fired up AppleWin on the 501, booted the disk images and used the apple II program "IIGIF" to convert the pictures into Apple II black and white hi-res binary format. I could have converted them in colour, or even double hi-res, but I wanted them to work on any 64k Apple II - and my IIe has a monochrome green screen
Anyway, after converting them all in the emulator and then throwing together a small applesoft BASIC program to cycle through them, I transferred them to my real Apple IIe using ADTPro - I did this using the audio features - Headphone/Mic ports on the 501 attached to the cassette in/out port on the IIe (this is an amazing program btw).
If anyones interested the disk image is here:

Still, its all part of the fun - and not too bad for a 25(ish?) year old machine
P.S. I wish I hadnt thrown out (well sent to the recylcers) my Image Writer I and its thunderscan cartridge
