Are you sending the files to your server? Which format are you using? multipart?

I have a table of images in my db, and I am saving the images as base64 in a filed type TEXT.

and then I am posting the table as xml to my server.

before I am posting to the server, i am inserting the rows of the table to a string
,but after a few rows I am getting out of memory error.

Images can produce very large base64 strings.

You need to have a good reason to convert the images to base 64. Why not use jRDC2 and just send the images as blobs? Will work faster and better.

You can write the strings to a file and then send them with Job.PostFile. The file will not be loaded into memory. You might get memory problems in other places.

I suggest to change the server site script to support fileuploads and read the data from the file uploaded, convert the file to base64 on Serverside and store the value in DB then.

Generally speaking it is a mistake to put images into the db. You should store the filename in DB and the file itself on Disc (webspace).

my problem with that is that every pic is associate to record in the customer db.

and I am not just uploading a file ,I am sending with every file a few parameters of the record id which is apply to in the customer db.

you can save the image under a filename associated with the db-entry....
