hi guys,
I am working on a project for printing Barcode from my current PHP page, the coding side is done, but I have really hard time to finding these Code39 and Code128 barcode images, just wondering if someone can help me on this.
Thanks a lot

I don't think you quite realise how barcodes work.

For the current code which how I generator the barcode on the label,
I created function and stored all the case (0~9, A~Z...etc) in code and those case (0~9, A~Z...etc) will link to a barcode image. if someone requested or scanned something like A123456789, then the function will checking the barcode image folder get the barcode images and combine together. Please advise

Well, the only problem that forsee would be that to accommodate using A-Z, a-z, 0-9 and [!@#$%^&*()] (total 72 chars) and picking 10 characters from that set, you would have to store about
3,743,906,242,624,490,000
images... unless my math is wrong, it has been a few years since i've done permutations...
3,743,906,242,624,490,000 x 6kb per image (conservative estimate) = 3.74390624262449e+18 * 6 kilobytes = 19.4839262 zettabytes
