When it comes to pics, size does matter. Finding the right balance between FILE SIZE and PICTURE QUALITY is essential when sharing your photos on line. If your images are too large then you might not be able to email more than a couple at a time or if you are uploading large images to a website or blog (or to TIC hint, hint) than your ginormous images are going to slow the site down and it will take forever to load your page when viewers are visiting your site. That’s not what we want. We want our images to be user friendly. This is called OPTIMIZING your images for the web. The process is not complicated but knowing more about how digital images are measured will make it easier. So let’s get into it.
USE PREVIEW TO RESIZE
The simplest way to change the size of your photos is to use PREVIEW which is the app that you use to open your images. After clicking on your photo and opening PREVIEW go to TOOLS and select ADJUST SIZE. The Image dimensions box will open.
PIXELS NOT INCHES
The first thing to understand is that digital images are measured in terms of PIXELS (px) not inches. Inches are only used when printing photos. Pixels refer to the lines on the screen. Horizontal pixels are measured in terms of the Width and the Vertical lines are measured in terms of Height.
Max Width = 1920px
Max Height = 1630px
For example the size of a full width image used as a header on a website is 1920px. That header image takes up the full width of your computer screen. The maximum height of your Vertical images should be no more than 1630 px. Compare this to the 3000-5000px width and height settings of your files straight out of the camera, way way to big. So let me show you an easy way to get your images down to a more managable 1920px width and 1630px heights.
- Make sure the boxes “Scale Proportionally” and “Resample Image are checked.
- If you are resizing a Horizontal image then set the Width first to a max of 1920px and because the “Scale Proportionally” box is checked the Height will automatically be adjusted.
- If it’s a Vertical image that you are resizing then set the Height first to a max of 1630px and the computer will automatically reset the width.
- Resolution in dpi/inch is another setting that is mainly for printing so if you are not going to print it then 72 dpi is sufficient.
Use On-Line Compression Apps
After you reset the width and height and resolution settings you swill see the original file size of your image drop considerably from a number in the MB’s to something ideally under 300KB’s. But if after resetting the height and width and resolution the file size is still high there is one more process that you can use that will bring the file size down as low as possible and that is something called compressing your image. There are a number of free apps on line that you can simply drag your files into and they will automatically compress them down to the lowest possible size without losing any noticeable image quality.

Taking a little extra time to resize and compress your imagesnwill make the process of emailing, viewing and uploading your photos so much easier. I know the TIC TEAM would love if we all would resize and compress our images before uploading them to our little web site. This would keep TIC feeling fast and fluid.
Ok, y’all so keep taking amazing photos, keep resizing and keep sharing them with the world . We love seeing your work.
