小程序image的src值长度有限制吗？

我想做上传图片添加水印，用的阿里云的oss图片上传，上传后获得的图片路径为：

https://smd-oss.oss-cn-hangzhou.aliyuncs.com/wechatApp/008ad97c9396.jpg

若是要实现水印效果，后面必须加长串的字符，添加后路径为：“https://smd-oss.oss-cn-hangzhou.aliyuncs.com/wechatApp/61bdb944ab97.jpg?x-oss-process=image/resize,w\_300,h\_300/watermark,type\_d3F5LXplbmhlaQ,size\_12,text\_,color\_FFFFFF,shadow\_50,t\_100,g\_sw,x\_10,y\_10”

图片报错无法显示
