I have just learnt how to resize my photos on Apple Mac. So, for those of you with the same computer, who do not know how to do it, I thought it might be of interest.
I discovered this last few days that Blogger only allows you unlimited free storage on 15 minutes of video and up to 800x600 pixels per photograph. This requires resizing the photos, which initially I thought meant reducing the size of the photo when I uploaded it on Blogger; but no, it is the pixels.
I had a feeling that Apple must be able to do this, and that it would be unnecessary to go into Picasa, Photoshop, etc.
I visited one or two Apple forums on the Internet, and one said 'Yes, I do it all of the time by going into Preview, then Tools, and finally Adjustments'. Now, for a novice like me that is just not good enough.
I got absolutely nowhere with that information, and decided to visit my Apple centre yesterday. I was told, that was correct, but advised how to do it. Keeping the instructions in my head until I got home, I then Skyped my eldest son in Norway so that he could go through the process with me. I know this all sounds pretty pathetic, but just having him with me helped.
How to do it:-
First of all you open a new folder and give it a name. I call mine 'blog photos'.
Then you go into your iPhotos and highlight the photo/photos you want to reduce for Blogger and export them to your new folder.
At this stage you can then go in to Preview and open it. Then go to Tools - open that and then go in to Adjustments - size. You may have to change in Adjustments from inches to cms. You then have a choice of the various pixel sizes.
The photo above is from my old camera, so not as good as my new one. I have reduced it to the 800x600 and I do not think that the clarity has suffered too much.
Hope this may be of assistance to someone.
Grateful thanks to all who helped - Olive, Gina, Perpetua, Christa, and Stardust, and others who offered valuable advice.
