Using base64 is good for small images and multiple requests, i.e. 100 images each 2KB big. Than you've so much requests that even with very small images slows down the page. When you've to store images bigger than a "thumb" size it may be not a good idea. For "wallpaper" size images it's good to store them as progressive JPGs. In your case maybe the converting process from image file -> base64 -> http response may not be the best solution. My advice is to run test with different scenarios that will answer all your questions. all the best, stoimen Hi Rithy,

Thanks you. I got it work now. I found that after php wrote the base64 string in a text file, the '+' sign is gone. But I've decided to store as normal image, I'll encode the normal image into base64 when php load the page. Because it could be 2 options which can use base64 or normal image and in ie6 doesn't support base64 image. But I'm not sure server will use how much cpu to encode the image... I'm considering about the usage of upc and ram of the server. Regards, Rithy Hi,

What will happen with your servers after 10 years storing all those images there? Probably the answer is there will be more and more servers. Well the situation with base64 is the same. The database will become larger and larger, but yet again there's a solution with clusters and/or more db server, right? If it's not working from a text file, that should be some other error, because base64 is just a string. Check for junk data into the text file. greetings Hi,

What will happen after 5 or 10 years? I've tried to save it into a text file, but after read it from the text file, it's not working....

On a particular request. So maybe the document becomes too big to be sent on the server. You should check the availability to upload via HTTP such large documents. If not you'd try something like FTP or whatever? greetings Well here I used it to “download” the document from the web. On a particular request.

I uploaded a document with multiple images. This document is sent back to the server for processing using an Ajax call. I have used Base64 for compressing the uploaded document. Issue: The document size becomes too bulky after Base64 compression & hence fails when the document is fetched. Any thoughts on this pls. regards, Satish I face a similar problem.

This is really strange to me, I doubt the tests you ran. Sounds strange! isn’t it, you cannot have the html response smaller than the http (multiple) responses of the images.
