WordPress plugin that validates uploaded images against configurable dimension, DPI, aspect ratio, and file-size rules before form submission, with a live client-side preview

Photographers, print shops, and real estate platforms upload thousands of images through WordPress forms and have zero native guardrails

Built for Content creators, photographers, and agencies using Contact Form 7 that need to enforce minimum image quality/resolution requirements..

The angle

Be the only CF7 and Gravity Forms compatible validator that catches bad images on the client side before upload rather than after server processing

“Replies: 19 I have created a form with a file upload field for images. I need to make sure uploaded images are of a certain min. size. Ex. 4000×3000 pixels. How…”

The receipts — real demand

Why this is a gap

Surfaced from a high-intensity complaint with clear willingness to pay and a specific, reachable audience.

The market

Content creators, photographers, and agencies using Contact Form 7 that need image quality enforcement. No search volume; signal is a forum post asking how to validate image dimensions, indicating isolated pockets of need.

Competition & the opening

Wedge play crowded — win on a narrow angle Moat 3/10 · thin angle Market 4/10 · small niche

Crowded market · 6/10 vs WP File Upload (Iptanus) — mature WordPress plugin with file-type/size restrictions and form integrationFilester (NSquared) — WordPress file manager plugin with upload restrictions including size and type filtersGravity Forms (with Add-Ons) — dominant WordPress form builder with file upload fields, size/type validation, and conditional logicWPForms — leading WordPress form plugin with file upload validation (size, type) built inAdvanced Custom Fields (ACF) — widely used field plugin with image upload constraints including size limitsCloudinary WordPress Plugin — handles image upload, transformation, and enforces dimension/format rules on ingest

Contact Form 7 is a plugin ecosystem; image validation is either done via server-side checks or third-party validators. The gap is a lightweight plugin that enforces minimum dimensions before upload without external dependencies.

What's hard to build

Client-side image dimension validation requires reading image metadata in the browser (EXIF), which varies by file type and browser support. Server-side validation is simpler but slower for users. Handling edge cases (rotated images, corrupted EXIF) adds complexity.

Why now

Contact Form 7 has no native image dimension validation; plugin ecosystem remains limited for pixel-based rules.
