1. Saving PNG, BMP etc.

Is there any reason why one can't save these images into a database as a blob data type? I'm thinking of barcodes as well as images of an item in inventory. I wouldn't want to save 10,000 to 50,000 as separate files in a directory.

Hi
A png file is just a file. Read the file into a sequence and save the sequence in the database.
To re create it just read the database numbers, and put them into a file, use the file, then delete the file. (it won't take long)
sqlite does blobs, though I'm not 100% sure how to use them (see the wrapper - if you wrap them better, let me know, and I'll incorporate it)
Heres a search for binary printing and getting

For windows graphics printing, DIB is your best bet. ALso the GDI plus graphics might give you some pointers
