JasperReports: duplicate images on report!

Hi, i have two reports embedded in a web page.

The problem is that they are two diferent reports. And Jasper put the generic name "image_0_0_0" on each image, and after it's generated by the ImageServlet. I mean:

Report 1 >>> image_0_0_0 (it's really a meter)
Report 2 >>> image_0_0_0 (it's a thermometer)

Maybe one aproach it's tell Jasper to change the name of the images on each report.

Report 1 >>> report1_0_0_0
Report 2 >>> report2_0_0_0

┬┐How can i do this?.

this is the solution: i've found it on the jaspersoft forums:

If you put both print objects on the session under the same name (ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE), the second object will overwrite the first one so when the first image will be requested, the servlet will actually extract it from the second report. So you need to use distinct names for the two print objects on the session:

Thanks lucianc!
