Does any body know of any custom tag for rendering image using a byte[]

i,e something like

<imagetag image="<%=form.getBytes() %>" height="<%form.getHeight() %>" width="<%form.getWidth() %>" />

No. And there could never be one. That's not the way HTTP works.

You would use a normal img tag and specify the src to point to the URL of a servlet that would serve up the image data.

I have already done that by creating a Image Servlet. But what i don't understand is why can't u do it through a tag. When you can have a iterator tag which accepts a Collection object, then you can always accept a byte array too.

Because HTML doesn't work that way. There is no meand to put the byte data directly into an HTML page and then expect theimage to show up. You must make a spearate request through an <img> tag.

JSP isn't any kind of magic that will make HTML do anything it can't do outside of JSP.

Oh, and please read this with regards to using words like "u". Thanks.

I never said html img will do it. I mean writing a custom jsp which has access to every object as servlet like OutputStream.

Still can't do it. JSP is a templating technology used to render HTML pages to be sent to the client. You cannot do anything with JSP that HTML cannot do. And HTML cannot render images with a byte stream embedded in a page.
