Hi,

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I think that re-sizing photos can be done by using Java in forms (see "Forms and Java" topic in the Forms builder on-line help about using Java in forms).

I am not a java person so I cannot help you more.

I know nothing about Oracle forms, but this problem is usually solved by requesting the picture to a service that does the transformation for you.

The basic idea is to make an HTTP request that you can use as if it was the direct path to the image but instead you pass the image identifier and the expected size and format in the querystring.

Ex: http://myserver/getimage?id=my_image_unique_identifier&x=340&y=220&format=jpg

In JAVA you can do it by implementing a simple REST service (with RESTEasy for example) that does the job.

Then you have to find a good image processing library or implement the thing yourself.
In JAVA I never had the need so I can't advise you properly here.
