试图解决别人的不太好的代码。任何想法将不胜感激。它似乎在<cfif>带来图像时爆炸：

<cfif LEN(qryCampers.std_image_filename[iRow + iCol]) GT 0>

如果我注释掉 if（并且只将与“no_image.gif”相关的部分保留在cfif语句之外）我们很好。文档出现。

CF Server 8，SQL Server 2000，图像尺寸相对较小（全部小于 30kb，宽度不超过 300px），此代码有时会起作用，当它起作用时，加载 PDF 需要永远。此特定查询（仅 12 条记录）导致错误。

错误：

Invalid image format

听起来在这一行<cfimage source="../photos/#qryCampers.std_image_filename[iRow + iCol]#" action="read" name="cardImage">中找到的图像不是有效的图像格式。你确定它试图读取的是图像吗？

您是否尝试过使用“isImage”？

 <cfif trim(qryCampers.std_image_filename[iRow + iCol]) neq '' 
          AND isImage('../photos/#qryCampers.std_image_filename[iRow + iCol]#')>

我同意@Leeish 的观点，即 CFImage 标签正在获取它无法识别为图像的东西。我曾经有过一段时间，我有一个标记为 jpg 的 jpg，我可以在浏览器中查看它，但后来我尝试在 photoshop 或类似的东西中将其拉起，我发现 jpg 本身存在一个前导问题这阻止了 cfimage 或 cfx_ImageCR （我更喜欢）。

至于您的无效图像错误，我们遇到了类似的格式无效和性能缓慢的问题。我们的解决方案是将图像转换为 png，然后使用 cfimage 转换回 jpg。我们在上传图片时这样做了，但您可以在您的情况下做同样的事情。 

<cfimage source="#expandPath('\images\temp')#\#cffile.serverFile#" action="convert" destination="#expandPath('\images\temp')#\#cffile.serverFileName#.png" overwrite="yes">
<cfimage source="#expandPath('\images\temp')#\#cffile.serverFileName#.png" action="convert" destination="#expandPath('\images\temp')#\#cffile.serverFileName#.jpg" overwrite="yes">
