Photos Instructions

This document describes the requirements of the ASCHG for Hike or Flower photos. In it, we list standards for photo shape and size, photo filenames, and photo captions. The objective is to have photos provided by different hikers and at different times fit seamlessly together in a photo gallery.

Allowed File Types

Allowed file types are jpg, jpeg, png, gif. All file extensions in image filenames must be lower case.

Image Shape and Size

  • Crop your photos so that they are (width x height): 1×1 (square), 4×3 (landscape), or 3×4 (portrait). (Banners are an exception.)
  • Resize the dimensions of your photos so that they have maximum dimension of 2000 pixels: 2000 x 2000 (square), 2000 x 1500 (landscape), or 1500 x 2000 (portrait). (Banners are an exception.)
  • Check the final file size. All photos are limited to 4000 KB (4 MB).

One free photo-editing program that can help you adjust your image shape and size is IrfanView (for Windows).


WordPress doesn’t accept some characters to be present in filenames of photos uploaded to the Media Library. So, change the filename to remove any special characters and punctuation such as:

   & $ % * ~ ( ) [ ] { } ” ‘ , ; .

Also eliminate any blank spaces. (Letters, numbers, hyphens, and underscores are OK.) Labeling filenames with the ID of the flower or hike lets us locate the relevant images more easily.

Locate on your computer the filenames of photos you want to upload and add the key for your flower or hike followed by an underscore to the beginning of the filename.

Some examples are:

  • F10384_IMG_6782_cs.jpg
  • F10397_SpottedCoralroot_c_VH.jpg
  • H10572_IMG_3366.jpg


Captions provide information about what the photo shows as well as who took it.

The overall structure for one of our photo captions is:

     [where or what] on [when] ©[year] [photographer]

Captions should not contain any commas in case they need to be imported or exported in a comma-separated-values (CSV) file.

Captions for flowers begin with where the flower photo was taken. Some examples are:

  • Sunset Canyon on 2016-05-16. ©2016 Joyce Oconnell
  • On the Holy Ghost Creek hike on 2015-08-13. ©2015 Marilyn Warrant
  • Full bush with petroglyphs in Piedras Marcadas Canyon on 2013-08-25. ©2013 Dawn McIntyre

Captions for hikes are similar, but begin with what the photo shows.

Some examples are:

  • View from the lunch spot on 2009-03-17. ©2009 Nancy Carr
  • Looking down into the valley on 2003-10-23. ©2003 Dick Brown
  • Frozen waterfall on 2013-01-24. ©2013 Joan Weissman
  • Small stream crossing on 2007-05-15. ©2007 Vivian Heyward

You can use the Caption Generator File to create your captions (you’ll need to have a newer version of Microsoft Excel on your computer). Click on “Enable Editing”. Then copy either row 3 or 4 into another row. Type or paste your information into the applicable column. The text in the your row under the Caption column should be your caption.

Alternatively, just copy one of the caption examples above and substitute the applicable information for your photo.

Associate the Caption with the Photo

You’ll need to get the caption associated with the image. One way to do that is to add it to the image IPTC metadata (different from EXIF metadata) using a photo editing software, such as IrfanView (for Windows).

Alternatively, you can edit the image caption “on the fly”.

On the Add Flower Photos page for your flower or the Add Hike or Edit Hike page for your hike:

  1. Click on the black Add File button then select your photo from your hard drive.
  2. In the vertical window that opens as the file uploads to the website, locate the Title and Caption boxes. The Title should already start with the flower or hike key.
  3. Copy your prepared image caption then paste it into the Caption box.
  4. Click on the black Save Changes button.
