ChangelogLast updated: 10 June 2026

Improvements

• added some automatic URL validation checks to highlight to developers when mismatches between base_url and the URLs given for locally stored EE Files Upload locations could lead to slower image processing and related javascript issues (#143)

Bug fixes

• where auto cache management failed to spot changes in images in file manager (#134)
• where cache audit interval advanced setting is always visible regardless of 'show advanced' toggle (#138)
• where the max and related max parameters are not being respected during image generation (#139)
• where colour fill fallback would not work if an image source was specified but not found (#140)
• where a source image ending in .jpeg would always get reprocessed even if a cached copy was present (#141)
• where sometimes a defective template might cause Image Pro to generate a php warning (#142)

Improvements

• responsive images using srcset parameter can now be specified using pixel-density format as well as width format (#133)

Bug fixes

• where parameter pass-through operation was inconsistent (#133)
• where preset full-edit mode for several parameters used default input field rather than custom entry screens (#133)

Improvements

• preload now works more elegantly with fetchpriority
• some useful changes in how Image Pro interacts with ExpressionEngine store and its license server
  for example the add-on now notifies users if there is an update available

Bug fixes

• where under some conditions an Ansel exception report relates to a fault involving a table linked to JCOGS Image (#117)
• where opening CP cache page generated insecure http traffic errors in browser console (#120)
• where when EE throttling is enabled, messages relating to this appear in the Image Pro error log report (#121)
• where watermarking using a transparent / gradient png where opacity less than 100 is also specified would generate odd results (#122)
• where some preset parameters have issues rendering controls in Full Edit mode (#123)
• where alt="" text is not always rendered in the generated <img> tag (#124)
• where heic library code might be flagged as a virus on some servers (#130)
• where there could be a conflict with unrelated Symfony modules (#131)

Improvements

• Cache writes now avoid double-encoding by writing already-encoded bytes directly when generating the main cached derivative.
• Added two extension hooks during cache writes to support companion add-ons (for example EXIF/IPTC/XMP metadata injection) without requiring Image Pro to re-read output from storage:
  • jcogs_img_pro_post_encode_image_bytes (post-encode, pre-write; allows byte-level modification)
  • jcogs_img_pro_after_write_image_file (post-write; optional side-effects/logging workflows)
• Responsive srcset generation now respects hard caps derived from max_width and max parameters (even when allow_scale_larger is enabled).
• Improved responsive srcset handling:
  • More permissive parsing for common width formats (e.g. 320w, 320px, 50%).
  • More tolerant srcset building when variant info is provided in different shapes.

Bug fixes

• where some border parameter configurations would be stripped by security validation before processing (#116)
• where Image Field could trigger a resize after a crop unnecessarily (#115)
• where setting fallback to colour field could prevent source image being processed (#114)
• where some small bugs in pro were closed (#113)
• where preset/edit class' javascript still included some debugging code (#112)

Improvements

• Ensure that the error log table does not get over-long due to loops generating multiple instances of the same error (#108)

Bug fixes

• where a pair tag processing run triggers a warning about bulk tag use (#107)
• where EE files meta data variables were not populating correctly (#109)
• where some unrelated Files system operations could trigger an exception error (#110)
• where clicking on 'view details' in error reporter doesn't show any errors (#111)

Improvements

• Redesigned Clear Cache and Audit buttons in Cache Location Details (#98)
• Optimisations to cached image processing to improve performance (#101)

• Where the cache_log table did not have indexes properly applied (#99)
• where use of 'empty' positional parameters might fail on some complex parameters (#100)
• where sometimes height and width variables were blank for cached images (#101)
• where fast cache detection was missing srcset variants, plus srcset not respecting allow_scale_larger parameter (#102)
• where some text prompts in add-on CP pages were inaccurate (#103)
• where CDN prefix definition in named connection is not being added to processed image path (#104)
