Thanks dima,
same as ur advice i've done it to have three detailed blocks and one master block, and i placed all the image panes on one canvas with the same dimensions and x,y coords and according to the requirement on the next image button i hide the current image and show the required image. so its doing well.
now some other problems are there i.e.
1. some of the images cant be displayed in the image pane and i rcv the message "can't read from the file specified " its just becos of image dimesions(large images-i cant set it in the camera).
2. when i'm on the last image, i want next button to be greyed, if i do it on the same button press it gives error message then where shoul i do that.
please help
thanks
