Resizing photos for a blog

Resizing photos for a blog

Hi,

I am having trouble taking photos that I have in iPhoto and uploading them onto a blog I have started (using Wordpress). I have a MacBook AIr, OS X10.8.5, Processor 1.3 GHz Intel Core i5, Memory 4GB 1600 MHz DDR3. I have an Olympus camera which I use to take my photos. I can get the photos off the camera and into iPhoto. Currently I edit them to make them look how I want them too, then save them, then export them, and save them again on my hard drive. Once I am in my blog I choose upload image and find the file on my hard drive. I have read another forum answer that said you can go straight from iPhoto without having to save somewhere else which I did not realise.

I make sure the file size is below 1MB as I have been told anything larger than this is too large and makes the site slow. Once I go to Export the photo, there is a window that comes up that asks how you would like to export it. I always export as a JPEG. I have tried exporting at all qualities (low to maximum), and all sizes (small to full size, and custom). When I try to customise the size I have tried many combinations of width and length, starting at 400 by 600 pixels (because a few people have told me that's a good size for photos online), up to about 1000 by 1200. I can only work out how to set the height OR the width though, not both, because it automatically changes the other to the size you have set the first one. Anyway, no matter what size I have chosen it always comes up small on my blog. It should fill the whole page. I think I might have had success once or twice with the size of the photo but any time I have the image is poor quality. I don't know why - this is all very new to me and I am hopeless with technology!

Your help would be SO appreciated! I am desperate to get my blog up and running!

Thank you so much

The answer depends on undisclosed information - what resolution is the screen you want to display this image on?

The new iMac has a 3840x2160 screen so to fill that screen your image must be at minimum of 3840x2160 - a very old IBM PC is 640x480 so you only need a 640x480 image to fill it's screen

Hi Larry,

Thank you so much for such a fast response! The only trouble is, I don't know that answer to your question about the screen size….Sorry!

At this stage I just want to see the pictures on my screen (which I think was 10 or 11 inches but I don't know what resolution it is, how do I/do I need to check that?) but in the long run I want to make the blog public so I guess I want the photos to display at a size that works on all computers. I am definitely NOT at all tech savvy, so that only thing I can think to say in answer to this question is that I want the photos to display like these ones do, on this website (as an example): www.apairandasparediy.com.

Will a photo that is 3840 by 2160 pixels going to be way bigger than 1MB?

Thank you again for your help!

Unless you know what you want no one can help - saying I have no idea what the resolution is but I what to fill it is like saying I have not picked a vacation destination yet but I want you to tell me the air fare - it is simply not possible

as to file size again without full details no one can answer - the file size is not determined just by the pixel dimension of the photo but alco by the JPEG compression you apply

for example here is one JPEG file size estimator - http://jan.ucc.nau.edu/lrm22/pixels2bytes/calculator.htm

here are the results of another showing that the JPEG file size for a 3840x2160 image can be between .35 an 5.35 MB depending on the setting you choose (smaller file being much lower image quality) and up to 49.8 MB as a 48bit TIFF

Until you determine the details no one can answer

Thank you for your help, I really appreciate it, I just don't know how to ask the right question yet. Back to Google for me for a while I think!

Thank you

There's a very good chance that this is a setting on Wordpress and nothing to do with what you are uploading. Check the options on your template. Most templates have conditions that govern the size of images displayed.

Hi Terence,

Thank you for your comment. Funnily enough this afternoon I went back to Wordpress and started having a look around and saw the image settings section which prompted me to start searching for information on sizing things for Wordpress. I haven't sorted it out yet but will keep searching. The settings in Wordpress are currently Thumbnial 150 by 150; Medium 300 by 300 and large 1024 by 1024. I know that this isn't the purview of the Apple support service 🙂 but thanks so much for letting me know that there is something else that might be the problem too.

Thanks again
