Tutorial; Resizing Images with Irfanview.

[Jaberwoc]

Hi all,
I feel some of our members may find this tut of use. What most of us take as an easy task can be a mystery to others. If this helps only a few people I think it's worthwhile. Hope you all agree.

To Size a picture for posting using Irfanwiew

1. Open your pic in Irfanview, then click on the image menu and select resize (see SS#003)

2. In the Resize window that opens, enter a width of 600-700 pixels,providing there is a tick in the "Preserve Aspect Ratio" box the height will automatically adjust. (see SS#004)
( 600-700 pixels width gives a reasonably sized picture to post). Click OK to resize the picture.

3. To save your picture, in the file menu select "Save As" and the Save window opens + a JPG/GIF Save Options window( see SS'005).
Give the picture a suitable title, note for convenience when posting I save the pic to Desktop, and note in the other window that the default PG compression is set at 80%, moving the slider lower reduces file size and picture quality.( See SS#006).
Try saving at this default setting. Minimise the window to expose the desktop, right click on your saved picture file and select properties, check that the file size is below the 100 KB required for posting by this board( see SS#007), if not return to Irfanview window, and move the slider to the left reduce file size, don't overdo this as the more you compress reduces your picture quality. Once satisfied you can save all for good and close Irfanview.

Note
While the above is applied to Irfanview, all other image progs will have similar means for resizing Pics.

Here's the testshot I used while writing the tutorial, I should display at a reasonable size.

that is the reason i seldomly resize w/irfanview, it's got some of the worse algorithms for decreasing file sizes i seen. please don't get me wrong-irfanview is a great proggy and the price is right.
for resizing you really can't beat photoshop elements .
i think it's even better than PSPro.
adobe rocks in this area.

Roy,
I've got to admit, I don't use Irfanview that much either, I did the tutorial in that because it's so popular. Oftener than not I use Picture Publisher 7.0 by Micrographix, I've used it since version 4.0 and got 7.0 with my scanner, so it's one image program I know fairly well, and am very comfortable with.

Bump, people seem to be still reading this, so I'll boost it to the top.

I've been working out of town for about two weeks. Got to come home for the weekend, then back again tomorrow. Hopefully I'll be home for good next weekend. Here's where I've been and what I've been doing if you're curious.

To Size a picture for posting using Irfanwiew

1. Open your pic in Irfanview, then click on the image menu and select resize (see SS#003)

2. In the Resize window that opens, enter a width of 500 - 600 pixels,providing there is a tick in the "Preserve Aspect Ratio" box the height will automatically adjust. (see SS#004)
( 500 - 600 pixels width gives a reasonably sized picture to post). Click OK to resize the picture.

Thanks for this info. I certainly can use this, as I'm a novice at using Irfanview. I also just ordered PSP 8 and am anxious to know how to learn to use it. Haven't received the CD yet, in the mail.

Well I was thinking I had posted a question or whatever into the thread not just the first bump. Sorry about that I looked at 1 picture and should have looked at all.
Need to keep this bumped more. LOL Easier to show this thread then explain it over a messenger.
Take care

Well, that works, thanks John for re-posting this thread and to Jack for originally posting this tutorial. I knew there was something simple I was missing, forgot about the compression settings. Seems, I am always trying to get the highest resolution for my pictures at home when printing, just couldn't get my mind to think in the opposite direction.

Thanks,

Craig

Your Welcome

See, each time you resave the photo (not open and close, but resave it) you sacrifice some image quality on the alter of high compression. Every time a JPEG is re-compressed, some of the "imperfect" information that was created when the photo was previously compressed is made even more "imperfect". Bottom line, the more you re-save a JPEG image, the more it's going to deteriorate.

Can I "save as" and use a different name and not loose quallity in my jpeg image. For instance image1__________save as image2. would image2 have less quality than image1?
