Hi Bob.

I read your faq recently and realized the importance of disposing images. That handled another problem I was having in the same application. Thanks.

However, when cycling images in the picture box, I cannot dispose of the image because I keep looping through the images and so I need all images to be displayed more than once.

I do something like the following (pseudo code):

int counter = 0;
Image images[] = new Image[5];
images[0] = Image.FromFile("image1");
images[1] = Image.FromFile("image1");
images[2] = Image.FromFile("image1");
images[3] = Image.FromFile("image1");
images[4] = Image.FromFile("image1");
this.Timer1.Start();

onTimerTick:

this.PictureBox1.Image = this.images[counter++];
if(counter == this.images.Length)counter = 0;

In theory, this should not cause any memory problems, right?

I have been testing my program again during the night and after running app. 6 hours, I only had an increase of about 200K. So maybe I don't have a problem anymore. However, I would still like a confirmation that the general procedure as described above should not cause any memory problems.

Thanks for being a great help to your fellow coders, Bob!
